R. G. Herb Condensed Matter Seminar
Modes are Modes: Parametric quantum information processing in superconducting circuits
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Jose Aumentado , NIST, Boulder
Abstract: I will give a brief overview of our work in utilizing parametric coupling to process quantum information in superconducting circuits. In the 2nd half, I will then discuss some of our ideas in continuously coupled multi-mode parametric circuits, and how expansion of the mode basis beyond the traditional two modes (signal+idler) can provide for more complex behavior including, for instance, the possibility of building in directionality, impedance matching, and even modifiying the gain-bandwidth constraint. As a simple example, I will discuss a 3-mode amplifier which has been realized in our group in an optomechanical circuit.
